Everyone talks about passenger vehicles as the killer market for self driving cars, but it isn't. One of my friends is a Paramedic and he told me the overwhelming majority of traffic fatalities he sees are a result of big rig truck drivers falling asleep. It would suck to put a whole industry of workers out of a job, but if you could reliably and cheaply transport large amounts of cargo with a self driving vehicle which never slept, that is pretty amazing. It would certainly up the profit of the distributors moving tons upon tons of cargo around the world every day.
